sql查询以基于文本和组ID返回项目

Question

我不确定如何最好地描述我要做什么（或为此搜索），但我将尝试。

我有一个预先存在的查询（存储过程），该查询基于3个特定的ID返回项目。 我想要做的是能够根据结果中具有完全相同的字符串的列进一步减少结果。 我希望查询返回其中某个列具有完全相同值的项目计数。

由于某种原因，我对如何执行此操作感到困惑，因此我对此绘制了一个完整的空白。

这里是当前数据的样本：

PROGRAMID   DAY TIMESLOT         SlotInfoDescription    TITLE
2688         4   13:00-16:30      Free Time              NULL
2688         4   16:30-17:10      NULL                 Joint Session with Search Engines: Machine Learning for Social Media Analytics
2689         4   13:10-16:00      Free Time              NULL
2689         4   16:30-17:10      NULL                   Joint Session with Search Engines: Machine Learning for Social Media Analytics
2300         4   12:00-13:30      Free Time
2300         4   16:30-17:10      NULL                   Joint Session with Search Engines: Machine Learning for Social Media Analytics

这是我想要的结果（基于标题相同）：

count = 1

这是当前查询：

    SELECT
    WS.PROGRAMID, 
    WS.ITEMID, 
    WS.DAY, 
    CASE datepart(weekday, dateadd(day, WS.DAY - 1, WE.EVENTSTARTDATE))
        WHEN 1 THEN 'Sun'
        WHEN 2 THEN 'Mon'
        WHEN 3 THEN 'Tue'
        WHEN 4 THEN 'Wed'
        WHEN 5 THEN 'Thu'
        WHEN 6 THEN 'Fri'
        WHEN 7 THEN 'Sat'
        ELSE 'N/A'
    END
    + ' ' + Convert(char(12), dateadd(day, WS.DAY - 1, WE.EVENTSTARTDATE), 101) as Date, 
    WS.TIMESLOT, 
    WS.SLOTTYPE, 
    WSSTC.DESCRIPTION AS SlotTypeDescription, 
    WS.SLOTINFO, 
    WSSIC.DESCRIPTION AS SlotInfoDescription, 
    ISNULL(WSI.TALKID, 0) AS TalkID, 
    LEFT(WPI.FIRSTNAME, 10) + ' ' + LEFT(WPI.LASTNAME, 10) + ' (' + LEFT(WEA.INSTITUTION, 10) + ')' + ' - ' + LEFT(WSI.TITLE, 10) + '...' + RIGHT(WSI.TITLE, 10) AS Talk, 
    WPI.FIRSTNAME, 
    WPI.LASTNAME, 
    WEA.INSTITUTION,

        DBO.WEBEVENTAFFILIATION WEA 
        ON 
            WPI.USERID = WEA.USERID

假设您正在使用SQL Server。 因为您知道存储的proc返回哪些列，所以可以执行以下操作：

create #tempTable ( columnsSprocReturns )
insert into #tempTable
exec yourSproc

select columns 
from   #tempTable
where  someColumn = 'someValue'

drop table #tempTable
